To all 107mm t may concern:

Be it lmown that l, WILLIAM J. Hiss, a citizen of the United States,residing in the borough of Manhattan, county, city, and State of NewYork, have invented certain new and useful Improvements in Conduit orCable Clamps and Bridle-Rings, of which the following is aspecification, taken in connection with the accompanying drawings.

My invention relates to the combination of a conduit or cable clamp andan open bridle ring, and also to the open bridle ring as asub-combination or article of manufacture.

My invention further relates to an open bridle ring preferably, thoughnot necessarily, formed of wire bent back on itself to form an open ringhaving one end unsupported, the ends of the wire being brought adjacentto each other to form a bifurcated spring shank. The two free ends ofthe wire are bent at an angle to the shank to cooperate either directlywith the conduit or cable clamp, or with a member carried by, orsupported on, said clamp.

In the figures, in which l have shown several embodiments of myinvention, the same reference numerals refer to similar parts in theseveral figures.

Figure l is a perspective view of one form of conduit or cable clamp;

Fig. 2 is a perspective view, similar to Fig. l, showing the bridle ringmounted on the conduit or cable clamp;

Fig. 3 is a perspective view of a dierent form of conduit or cable clampin which a carriageor supporting member is held to the conduit or cableclamp, the bridle ring being supported by the carriage;

Fig. 4 is a perspective view of a modiiied construction in which thecarriage of F ig. 3 is reversed and used to support the bridle ring on awall or other suitable support independent of aconduit or cable clamp;

Fig. 5 is a perspective view of another form of conduit or cable clamp;l

Fig. 6 is a perspective view of the conduit or cable clamp shown in Fio.5, with the addition of a different form of supporting member orcarriage and the open bridle ring; l

Fig. 7 is a perspective view of the supporting member or carriage shownin Fig. 6 used alone to support the bridle ring upon a wall or othersuitable support;

Fig. 8 is a perspective view of the preferred form of open bridle ringhaving a bifurcated shank;

F ig. 9 is a perspective View of a diderent form of conduit or cableclamp;

Fig. l0 is a perspective view of the conduit or cable clamp shown inFig. 9 with the addition of the bridle ring;

Fig. ll is a perspective view of a different form of conduit or cableclamp in which bearings are stamped up from the base;

Fig. l2 is a perspective view of the same conduit or cable clamp asshown in Fig. 11, but with the addition of the bridle ring.

ln the commercial use of conduit or cable clamps it is not generallypossible, at the date of the original installation, to determine whetheror not bridle rings willV be needed to support additional loose strandsof bridle wires. ln commercial practice, a cable is supported on a wallor other suitable support and it may be weeks, months, or years laterthat the telephone engineers will determine that it is desirable tosupport bridle wires parallel to the cable.

By my invention the conduit or cable clamp may be used as a separatearticle of manufacture or sub-combination, and then later, when theneeds of the service demands it, my bridle ring may be supported by thesame conduit or cable clamp, when the complete combination would beused.

ln my invention l have shown several different forms of conduit or cableclamps all cooperating Vwith my open bridle ring to form completecombinations.

ln Figs. l to 2, for example, the cable l is supported on the wall orother suitable support 2, by the conduit or cable clamp 3 having a hookportion 4, the base 5, and the reinforcing member 6. This reinforcingmember is preferably formed integral wit the base 5 and bent back uponit as shown in Figs. l and 2. 'lhe end 7 of the reinforcing member Gisbent at an angle to forml two wings 8 and 9, which bear upon the lowersurface of the hook portion Zl, and serve' as a support for the same.The screw l0 secures the conduit or cable clamp upon the wall or othersuitable support 2.

l provide the wings 8 and 9 with any suitable means to coperate and holdthe bridle ring l1. Preferably these coperating means are the holes 12,l2 which are stamped or Otherwise formed in the wings .8 and 9.

Vhen the cable 1 is originally installed simply the cable clamp 3 wouldbe used, as shown in 1. W`eeks, months or years later when the tratlicload becomes excessive, and the telephone engineers desire to increasethe capacity without going to the eX- pense ot mounting larger cable, itis merelyr necessary, by my invent-ion, to secure the open bridle ring11 to the wings 3 and 9.

rlhis bridle ring may be formed in various ways. Preferably, though notnecessarily, l 'lorm it Jfrom wire bent back on itself to torni an openring 13 having an unsupported end 14:, the two strands ot' the wire 15,15 being brought adjacent to each other to torni a spring shank; thevery ends 16, 16 are bent away from each other to form a bifurcatedshank and engaging arms to coperate with suitable engaging surfacescarried by the conduit'or cable clamp, or by a supporting member orcarriage held thereto.

1n the construction shown in Figs. 1 and 2 it is merely necessary tohook one of the arms 16 in one ot the holes 12, 12 and then bymanipulation compress the strands 15,` 15 together so as to permit theother arm 16 to spring into the other hole 12, when the open bridle ring11. will be securely held to the conduit or cable clamp 3. The runs otbridle wires 17, 17 can then be threaded through the open ring 13 in theusual manner.

Should it ever be desirable to remove these bridle wires 17 andthebridle ring 11, this may be easily done by compressing the spring shanksuiliciently to withdraw one ot' the arms 16 from its coperating holewhen the other arm can be then readily withdrawn. The bridle ring may beused again in any other location `with a cable or conduit clamp orcarriage adapted to cooperate with it.

1n Figs. 3 and 4 l have shown a` conduit or cable clamp 18 having a hookportion 19, and a base 20, both ot one thickness ot metal. rlhe base 20is preferably provided with a lip or tlange 21 to coperate with asupport-V ing member or carriage 22. y

Ordinarily the cable 1 will be supported by the conduit or cable clamp13 without the addition oi' the bridle ring 11. it is desirable toincrease the capacity of the installation, it is merely necessary, inthis term ot my invention, to loosen the securing screw 10 slightly, soas to permit the supporting member or carriage to ,be slipped under thehead of the screw 10, the screw passing through theV slot 23. By thentightening up the screw 10, the end 241 oi the carriage is brought backoi; the lip or flange 21 and serves to securely hold the supportingmember or carriageto the conduit or cable clamp. This supporting memberor carriage 22 is provided with any suitable cooperating means tosupport the bridle ring 11. Preferably it is provided with` the Wheneverholes 25, 25 for this purpose. After the carriage has been secured inposition and the head ot the screw 10 tightened, the arms 16, 16 can besprung into the hole 25, 25 in the same manner as previously describedin connection with the forms shown in Figs. 1 and 2. Y

1n some cases l may desire to support the bridle ring 11 without using aconduit or cable clamp. 1 have shown one such form of my invention, butto which l am not to be limited, in Fig. 4, where the removable orsupporting carriage 22 is shown in reverse position, and secured to thewall or other suitable support 2, by the screw 10. Of course, thecarriage could be arranged with the slot 23, as shown in Fig. 3. Whenthe carriage is used alone, however, it is preterably reversed as shownin Fig. Ll, so that the screw 10 will become seated in the upper closedportion of the slot. Y

1n some cases 1 may use a conduit or cable clamp 26, Figs. 5 and 6,having a` hook portion 27 and a base 28, both ot one thickness of metal.Preferably, though vnot necessarily, 1 provide thelower end of the base28 with a fla-nge 29 as shown in Fig. 5. In this form of my invention,when it is desired to support runs of bridle wires 17, the head ot thesecuring screw 10 is loosened slightly to permit the horizontal Vslot 30in the removable supporting member or carriage 31 to slip horizontallyunder the head 10 of the securing screw. The head of the screw 10 isthen tightened which will hold the carriage or supporting member 31firmly to the conduit or cable clamp 26. The open bridle ring 11 is thensecured to the carriage 31 by simple manipulation in the manner.previously described.

In some cases where it is desired to support the open bridle ring 11 toajwall or other suitable support 2 without the aid of a conduit or cableclamp, it is merely necessary to screw the screw 10 through the slotV30, Fig. 7 and then, or previously, attach the bridle ring to thecarriage or support 31.

1 may form my conduit or cable clamp 32, Fig. 9 with a hook portion 33,and a base 34;', both ofl one thickness of metal. The lower portion ofthe base is provided with two tines 35, 35 and an interposed slot 36.The ends ot these tines are'bent back upon themselves, tormingbearings37, 37 for the arms 16, 16 of the bridle ring 11, as shown in Fig. 10. i

Instead of forming the base with two tines I may employ a conduit orcable clamp 38, Fig. 11, having a hook portion 39, and a base' 40, fromwhich is struck up two bearings 41, fil. The arms 16, 16 ot the bridlering 11 lit in these bearings. A portion of the shank ot the bridle ringrests upon the lower portion of the base 40, Fig.12.

,In all forms of my invention itis to be noted that the conduit or Cableclamp may be used separately from the open bridle ring, and that thisopen bridle ring may be added at any future time by simple manipulation.It will also be noted that in my invention no tapping or screw-threadingof the conduit or cable Clamp is required, and that it is not necessary0r desirable to screw-thread the bridle ring, all 01" which savesexpense in manufacture.

Having thus described this invention in connection with illustrativeembodiments thereof, to the details of which I do not deside to belimited, What is claimed as new and What is desired to secure by LettersPat-V 15 ent is set forth in the appended claim.

-What l claim is A neuT article of manufacture comprising an open bridlering having one of its ends unsupported, its other end being bifurcated20 and provided with means to ooperate with a conduit or cable clamp.
